Title: Method and apparatus for detecting a constituent in an  atmosphere
IPC: G01N27/64
Filed: 1973-05-08
Abstract: 1438504 Gas analysis ANALYTICAL INSTRUMENTS Ltd 8 May 1974 [8 May 1973] 21839/73 Heading G1N The invention relates particularly to the detection of vapours from organic-nitro-compounds in air. APPARATUS. As shown Fig. 1 the air inflow divides into two conduits 2, 3 passing silastomer membranes 6, 7, permeable to heavy organic (nitro) vapours. The vapours are transported by argon carrier gas to electron-capture-gauges 15, 16. Organic-nitro-compounds in conduit 2 are broken down by heater 18 and do not pass through membrane 6. The heater may alternatively be placed between the membrane 6 and gauge 15. CIRCUIT. The difference signal from the two channels is affected by ion current drift due to e.g. varying level of contaminants such as halogenated hydrocarbon pesticides, deposits, polarization. This ambient drift is compensated by a kind of delayed AGC in one channel. As shown Fig. 2 amplifier 23 in one channel has its gain controlled so that the output of the difference measuring amplifier 24 is normal zero. A second difference amplifier feeds a slope detector 27 to hold the gain when a large increase appears due to the sudden detection of nitro-compounds.

Title: New hardeners of epoxy resins, a process of making same and products produced therefrom
IPC: C08G59/50
Filed: 1959-06-30
Abstract: Hardeners for epoxy resins comprise compounds of formula <FORM:0920514/IV(a)/1> in which X represents -CH2NH2 or a substituted acid amide group, any substituent in the amide group still containing a primary or secondary amine group, Y is hydrogen or the grouping <FORM:0920514/IV(a)/2> m is 7 or 8 and n is 8 when m is 7, and 7 when m is 8 (see Group IV(b) ).  The hardeners are non-volatile and of low viscosity and are suitable for solvent-free lacquers, casting or laminating material or reaction adhesive.  Examples describe the use of a mixture of 1:9 and 1:10 diaminooctadecanes, a mixture of 9- and 10-amino-stearic acid amino-amides, and a polyamido-amide as hardeners for an epoxy resin derived from diphenylolpropane and epichlorhydrin to give cast, moulded or a film-forming coating, or for solutions of the resin in xylene-methylisobutyl ketone and xylenemethyl glycol to give film-forming lacquers.ALSO:The invention comprises compounds of formula, <FORM:0920514/IV(a)/1> in which X represents -CH2NH2 or a substituted acid amide group, any substituent in the amide group still containing a p- or secamine group, and Y represents hydrogen or the grouping <FORM:0920514/IV(a)/2> m is 7 or 8 and n is 8 when m is 7 and n is 7 when m is 8.  the compounds are prepared by reacting an unsaturated fatty acid amine with hydrocyanic acid in the presence of concentrated sulphuric acid, and hydrolysing the formylamino compound, or alternatively by reacting an unsaturated fatty acid with hydrocyanic acid in the presence of sulphuric acid, hydrolysing the formylamino compound to the amino acid and if desired reacting after esterification, either with a polyamine to the corresponding amino amide or converting into a urea compound by reaction with phosgene in the presence of an acidbinding agent and then reacting with a polyamine to a polyamide amine.  The products, for example, a mixture of 1 : 9 and 1 : 10 diamino octadecanes, 9- and 10-aminostearic acids, and a polyamino-amide derived from the action of diethylene triamine on carbonyldi(aminostearic acid) are non-volatile and of low viscosity and may therefore be used as hardeners for epoxy resins in solvent-free lacquers or as casting and laminating, or adhesive resins.
